Requests that the current message be queued for delivery.
Form objects call the IMAPIMessageSite::SubmitMessage method to request that a message be queued for delivery. The message site should call the IPersistMessage::HandsOffMessage method before submitting the message. The message does not need to have been previously saved, because SubmitMessage should cause the message to be saved if the message has been modified. After the return of SubmitMessage, the form must check for a current message and then dismiss itself if none exists.
